Calibrate the Rain Gauge
The rain gauge on the 5-in-1 sensor can be calibrated to improve accuracy.
Items Needed
: 5-in-1 sensor, companion unit, plastic cup, pin, screw driver
1. First, ensure 5-in-1 sensor is perfectly level using built-in bubble level.
2. Use compatible companion unit or AcuRite software to monitor during calibration.
3. Make a pin hole in the bottom of a plastic cup. Hold the cup over the rain gauge and
fill
it
with
exactly
1
cup
(8oz)
of
water,
allowing
the
water
to
drip
into
the
rain
gauge.
You
should hear the internal buckets tip and see water drain through the rain gauge.
4. A few seconds after each bucket tip, the companion unit displays rainfall in
approximately 0.01” or more increments.
5. The cup of water should take more than 20 minutes to empty; a quicker period will result
in inaccurate calibration. Try to simulate a normal steady rainfall. When cup is empty of
water, companion unit should register 1.06”
Tips
• There should be nearly an equal number of water drops (about 25 water drops) between
bucket tips. If not, adjust the calibration screws on the bottom of the 5-in-1 sensor until an
equal number of water drops are tipping the buckets.
Adjustment
If
the
rain
gauge
doesn’t
register
close
to
1.06”,
make
an
EQUAL
adjustment
to
the
two
calibration screws on the bottom of the 5-in-1 sensor. Turning screws clockwise increases
rainfall; counter clockwise decreases rainfall.
• To adjust the rainfall reading by 2% turn both screws 1/8 of a turn.
• To adjust the rainfall reading by 4% turn both screws 1/4 of a turn.
• To adjust the rainfall reading by 8% turn both screws 1/2 of a turn.
